This invention relates to improvements in fountain pens.

'I'he general object of the invention is to provide a fountain penhaving a novel ink container.

Another object of the invention is to provide a novel ink container fora fountain pen.

Other objects and the advantages of this lnvention will be apparent fromthe following description wherein:

l Fig. 1 is a side elevation of my improved fountain pen partly insection;

Fig. 2 is an -enlarged fragmentary central section through the penshowing the ink vial being positioned in the barrel;

Fig. 3 is a view similar to Fig. 2 showing the ink vial fully positionedin the barrel; and Fig. 4 is a View similar to Fig. 3 showing amodification of my invention.

Referring to the drawing by reference char-A acters I have indicated myimproved fountain pen generally at IIJ. As shown the fountain pen I0includes a barrel portion I2 having a recess I3 therein which opensthrough one end of thel barrel and a reduced communicating recess I4which opens through the opposite end of the barrel. At the juncture ofthe recesses I3 and I4 the barrel'includes a shoulder I5 which is shownas bevelled. Adjacent its outer end the recess I3 includes a threadedsection I6 and adjacent the opposite end of the barrel the barrelincludes an externally threaded portion I1.

Adjacent the threads i1 a pen point i6 which may be of any desired typeis secured to the barrel I2 by a plug member i9. This plug I3 includes abody portion 20 which ispositioned in the recess I4 and includes areduced lip portion 2l and a reduced conical spur portion 22. The lip 2Iextends outward from the end of the barrel I2 and has an ink groove 23therein which is disposed below the ink aperture and slit 24 of the pen`point I3. At the end opposite to the lip 2| the plug I9 has a spurportion 22 which is shown as separately formed. and which is preferablymade of metal while the body 20 may be made of hard rubber. The spurportion '22 has an end 22EL which fits within the body 20 and is held inplace by a pin 22h. The spur portion 22 extends towards the threads I6to a predetermined distance beyond the shoulder I5.

The plug I9 has a recess 26 therein which at one end opens into thegroove 24 and at the opposite end extends to a point adjacent the apexof the spur portion 22. Furthermore, the spur portion 22 has a pluralityof apertures 21 therein adjacent the apex thereof which open into therecess 26. Acap 28 f the usual type is shown as removably secured to thebarrel I2 by engagement with the threads I1. At 29 I have indicated anink vial which includes a hollow cylindrical body portion 36 open at oneend and 5 closed at the opposite end. Adjacent the closed end the vialincludes an enlarged threaded portion 3I and an enlarged head portion32. Adjacent the open end of the vial the body 36 has an externalcircular groove 33 therein. l0

For closing the open end of the vial I provide a cap member 34. The cap34 is cup-shaped and is made of rubber and fits over the open endof thebody 36.v The cap 34 includes an enlarged annular flange portion 35, aportion of which is l5 positioned in the groove 33 and tightly engagesthe body 30. The bottom of the cap 34 includes a thickened portion 33which extends into the body 30. 'I'he vial 29 is adapted to be lled withsuitable fountain pen ink. 20

In operation a vial 29 is inserted in the barrel recess I3 with the vialcap 34 directed towards the spur 22. When the vial cap 34 engages thepointed end of the spur 22 and the vial is moved further into the barrelthe pointed end of the 25 spur 22 punctures the bottom of the cap andpasses through the thickened portion 36 into the interior of the vial.As the'vial is moved into the barrel the vial threads 3l engage thebarrel threads I6 and then the vial is rotated to move 30 the cap flange35 into tight engagement with the shoulder I5 of the barrel.

When vthe vial is fully positioned in the barrel the apertures 21 in thespur 22 are positioned in the vial beyond the cap so that the ink inthe35 vial will, when the pen is used to write, flow through the apertures21 int'o the recess 26 and then into the ink groove 24. When the ink inthe vial is exhausted the vial is removed from the barrel and anothervial inserted thereinto. 40 When the vial is removed the elasticity ofthe cap closes the puncture made by the spur 22. Thus should any inkremain in the vial it will not leak out when the vial is removed fromthe pen barrel. 45

' In Fig. 4 I have indicated armodied form of my invention generally at31. As shown the barrel, plug and pen point of the device 31 are similarto those of the device I0 and like portions thereof are indicated bysimilarly primed refer- 50 ence numerals. In the device 31 I provide acap member 38 for closing the open end of the barrel I2. The cap 38includes an externally threaded portion 39 for engagement with thebarrel threads I6' and an enlarged portion 4I).` The 55 cap 38 has arecess 4| therein which opens through the end thereof opposite the headportion 401, Positionedin the recess 4| I provide a pad 42 which may bemade of sponge rubber and a disk 43 which is made of a suitable hardmaterial. The pad 42 is preferably cemented to the cap at the bottom ofthe recess 4| and the disk 43 is preferably cemented to the pad 42.

For use in the device 31 I provide an ink vial 45 which is shown as ahollow tube 46 which may be made of metal and is closed'at one end by ahemispherical end wall 41. Adjacent its open end the tube 4B includes anenlarged peripheral ange 48. The open end of the tube 48 is closed by acap 48 which is cup-shaped and made of rubber. The cap 49 includes anenlarged flange portion 50 which engages the tube flange 48. The bottomof the cap includes a thickened portion 5| which extends into the tube.

In operation the cap 38 is removed from the barrel and a vial 45 ispositioned in the barrel recess I 3 with the vial cap 49 engaging theend of the spur 22'. The barrel cap 38 is then positioned in the end ofthe barrel with the curved end 41 of the vial positioned in the caprecess 4| and engaging the disk 43. Thereafter the cap 38 is rotated toengage the cap and barrel threads. Thereafter as the cap is furtherrotated it moves the vial further into the barrel and causes the pointedend of the spur 22 to puncture the vial cap 49 and enter the tube 46. Atthe same time the vial cap is being punctured the pad 42 is beingcompressed so that when the cap 38 is in a fully closed position the pad42 through the disk 43 resiliently urges the vial towards the shoulderl5' thereby compressing the flange 50 of the vial cap between theshoulder I5' and the tube flange 48.

From the foregoing description it will be apparent that I have provideda novel fountain pen and vial which is simple in construction and highlyefficient in use.
